From the record

“The Tintic Standard Reduction Mill - also known as the Tintic Mill or Harold Mill - built in 1920, and only operating from 1921 to 1925, is an abandoned refinery or concentrator located on the west slope of Warm Springs Mountain on the southern edge of Genola, Utah, United States. In 2002, the Utah Department of Environmental Quality tested the soil and found it contained high levels of arsenic and lead, which can lead to serious health problems and even death.”

Storms near this property

2 since 2013

Regional context, not property-specific evidence. The National Weather Service names Goshen, the town this property stands in, in 2 storm reports between 2013 and 2016: 1 flash flood, 1 hail. No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office filed it, from the NOAA Storm Events Database, and each date opens the federal record of that event.

When	Event	Place named	Harm	What the report says
September 2013	Flash Flood	Goshen	$900,000	Heavy rain caused flash flooding across much of urban Utah County, with multiple locations recording 0.6-0.8 inches of rain in only 15 minutes. The most significant damage from flooding was reported in Provo, Orem, Payson, and Santaquin. Street flooding was widespread and some roads incurred major damage, with the worst damage occurring at 900 North and Grand Avenue in Provo, where water undercut and washed out a large portion of the asphalt road. Debris from the storm was scattered across most local roadways, taking several days to clean up, and even closed some roads for a period of time. Flowing water caused also caused significant damage to large concrete stairs at Lions Park in Provo. At University Mall in Orem, water quickly filled the parking lot, submerging many cars in more than a foot of water. \|\|Residential areas also received significant flood damage. In Provo, at least 25 homes had major damage, with more than 50 receiving minor damage. In Orem, approximately 30 homes received flood damage. In Santaquin, about 30 homes had flooding a foot deep or more, while about 30 other homes had flooding with less than a foot of water. Water wasn't the only problem in Santaquin, as the storm drainage system became overwhelmed, and raw sewage flowed into many homes. \|\|Finally, the flooding also impacted Timpanogos Cave National Monument, where heavy rain and associated debris stranded 150 hikers for several hours, before rangers were able to clear a path and rescue them. The Monument was closed for two full days while debris was cleaned up from both the hiking trails and nearby State Route 92.
May 2016	Hail	Goshen	-	Penny sized hail was reported south of Santaquin.
